The Chrome User Experience Report is powered by real user measurement of key user experience metrics across the public web, aggregated from users who have opted-in to syncing their browsing history, have not set up a Sync passphrase, and have usage statistic reporting enabled....

I've got to confess this all does not yet come trippingly off the tongue. If anyone has a really intuitive feeling for the available data sets and interlocking tools, I'd love to see them summarized.

Pagespeed Insights tool gives me different mobile report info than Google's other speed report tool: [testmysite.thinkwithgoogle.com...] for the same pages. In fact, there are significant differences on some reports.

From the topic of this thread, I'm assuming the PS is reporting Chrome stats and the other tool is using some type of HTTP client.
